Explain SMBC — the wiki for Saturday Morning Breakfast Cereal

This comic shows a man enthusiastically brandishing a knife while declaring, "Math is gender neutral! And if you disagree, you will be too!" The woman next to him recoils in alarm. The caption below reads, "I plan to raise confident daughters."

The humor lies in the absurd escalation: the man's heart is in the right place -- he wants his daughters to grow up knowing that math ability has nothing to do with gender. However, his method of advocacy (threatening violence against anyone who suggests otherwise) is wildly disproportionate and unhinged. The joke plays on the tension between a progressive, well-intentioned message and an extremely aggressive delivery, satirizing the idea of a parent who is so passionate about gender equality in STEM that they become comically threatening.
